This Black-Tip Cat-Back Exhaust System upgrades 2018–2025 Mustang GT 5.0L models with a deep, aggressive performance tone and increased exhaust flow. Featuring a straight-through muffler design and mandrel-bent T304 stainless steel tubing, the system enhances power while maintaining a refined, non-drone cruising character.
